[MiniProject] Convert Vietnamese unicode strings to unaccented strings

 Recently, I embarked on an exciting Arduino project where I needed to convert Vietnamese Unicode strings into their unaccented equivalents. The goal was simple, but I quickly ran into a problem: the conversion process wasn’t working as expected. Characters like "Độc lập tự do" were returning as a string of question marks!

I reached out for help and discovered that the issue was rooted in the way UTF-8 encoding was handled in my code. With some guidance, I learned how to properly decode UTF-8 characters into their Unicode equivalents before converting them. By breaking down the string into manageable arrays and thoroughly testing each case, I finally got the correct output: "Doc lap tu do."

This project taught me the importance of understanding encoding and the value of community support in problem-solving. Now, my Arduino project runs smoothly, converting Vietnamese text as intended!


The serial Monitor output:

Note:
This project comes easy if you have already had some experience with Arduino, LCD 16x2 shield,  C/C++ programming, Unicode encoding, testing techniques, and AI literacy. If you don't know those things, don't be afraid, just google it or contact me. I am happy to help you with one week's feedback.

[STM32] How to configure Timer 1, Channel 3 is PWM 1kHz, duty cycle 20% to control BLDC motor

 To configure Timer1 for a 1 kHz PWM signal with a 20% duty cycle on an STM32H7S3L8 microcontroller, follow these steps: 1. Understand the Timer Parameters PWM Frequency : 1 kHz → Period = 1 ms. Duty Cycle : 20% → ON time = 0.2 ms. The timer’s clock frequency is derived from the APB clock (e.g., TIMCLK). Let’s assume you know the APB clock frequency. The Timer prescaler and auto-reload register (ARR) define the PWM frequency. 2. Compute Timer Parameters Formula: PWM Frequency = Timer Clock (Prescaler + 1) * (ARR + 1) \text{PWM Frequency} = \frac{\text{Timer Clock}}{\text{(Prescaler + 1) * (ARR + 1)}} PWM Frequency = (Prescaler + 1) * (ARR + 1) Timer Clock ​ For 1 kHz PWM: A R R = Timer Clock PWM Frequency ∗ ( Prescaler + 1) − 1 ARR = \frac{\text{Timer Clock}}{\text{PWM Frequency} * (\text{Prescaler + 1)}} - 1 A RR = PWM Frequency ∗ ( Prescaler + 1) Timer Clock ​ −...

[AI] How to pass ATS (Applicant Tracking Systems)

  When it comes to passing through the initial screening by AI (Applicant Tracking Systems or ATS), it's important to optimize your resume for the specific keywords and formatting preferences that these systems use. Here are some tips: Use Relevant Keywords: Identify keywords from the job description and include them in your resume. ATS systems look for matches between the job requirements and your resume content. Keyword Placement: Integrate keywords naturally throughout your resume, especially in the skills, experience, and education sections. However, avoid keyword stuffing; ensure the language remains clear and coherent. Simple Formatting: Stick to a clean and straightforward format. Avoid complex designs, tables, or graphics that may confuse the ATS. Use standard fonts and keep the layout consistent. Use Standard Headings: ATS systems are designed to recognize specific sections. Use standard headings such as "Education," "Skills," "Experience," an...
